Title: Improvements relating to cabinets for the storage of gramophone disc records and the like
IPC: A47B81/06
Filed: 1932-08-25
Abstract: 406,350. Gramophone record &c. cabinets. FRASCHETTI, V., 54, Norfolk Square, Hyde Park, London. Aug. 25, 1932, No. 23777. Addition to 312,787, [Class 18]. [Class 18.] The invention described in the parent Specification is modified in that the gramop h o ne records &c. are stored in the compartments of a case 1 and in the form shown in Fig. 1 are ejected by means of a tilter 12 and a sliding rod 11 with which each compartment is provided the rod 11 being engaged by a plunger 9 working in an aperture in a head 8 which slides on a spindle 7 so that it may register with any record desired.

Title: Improvements in turret lathes
IPC: B23B29/00
Filed: 1933-08-26
Abstract: 405,911. Lathes. HEINEMANN, W., 25, Friedrichstrasse, St. Georgen, Schwarzwald, Germany. Aug. 26, 1933, No. 23786. Addition to 394,574.

Title: Improvements in weighing scales and the like
IPC: G01G3/02
Filed: 1923-09-25
Abstract: 216,424. White, A. E., (Dayton Scale Co.). Sept. 25, 1923. Indicating-mechanism-A weighing scale has means acting on the scale beam to oppose the pull of the load, the operation of the means being controlled by an electric power device which is, in turn, controlled by a pair of contact devices associated with the beam and co-operating with means for controlling the operation of the electric power device to initiate a weighing cycle when the beam engages one of the contact devices and co-operating with other means for controlling the operation of the power device to terminate the weighing cycle when the beam engages the other contact device. The weight to be measured pulls upon a draw rod 3 and brings the beam 1 into engagement with an electric contact 15 carried by a bent lever 17 thereby energizing magnets 23, 12, and a solenoid 6. The magnet 23 attracts a bent lever 18, thereby moving its contact 16 slightly towards the beam, and also completes a circuit through a contact 26 to maintain the circuit of the magnet 23 independently of the contact 15. The solenoid 6 being energized raises a rack 4 connected to the beam by a spring 2 or equivalent. As the pull on the beam increases, the beam leaves the contact 15 and at the balancing point touches the contact 16 whereupon a circuit is established through a relay magnet 31 and contacts 25. The magnet 31 attracts its armature and separates the contacts 25 thus breaking the circuit through the solenoid 6 and magnets 12, 23. The solenoid 6 ceases to pull on the beam and the rack 4 is retained by a spring-actuated pawl 11 liberated by the magnet 12. The magnet 23 liberates the bent lever 18 which falls away fromi the beam into its normal position. The weight on the scale is now indicated by a, pointer 9 actuated from the rack 4. Owing to the solenoid circuit being broken at the contacts 25 injurious sparking and pitting at the beam contacts is avoided and inaccuracy is minimized. When the load is removed 'from the scale or is reduced in amount, the magnets 34, 12 are energized and the rack 4, under the influence of the spring 2 and gravity, descends until the beam moves up to the contact 15 and in a manner similar to that described above is restored to the balancing position. Specification 182,665 is referred to.

Title: Improvements in and relating to sound records and means of and apparatus for producing the same
IPC: G11B3/08
Filed: 1923-09-27
Abstract: 231,538. Emerson, V. H. Sept. 27, 1923. Records, duplicating; blanks; tools for recording.-Relates to sound records and apparatus for producing them by mechanically copying a master record upon a blank. According to the invention, the blank employed consists of homogeneous malleable material, preferably aluminium, upon the plain surface of which the copy is produced by scoring or compression of the material as distinguished from cutting or removal of the material the thickness of the blank being substantially greater than the depth of the groove scored therein. The object is to obtain a sound groove the walls of which are smooth and burnished, so that undesired irregularities occurring in the groove in the original record are not present in the copy. In the apparatus shown, a blank disc c preferably consisting of metal having paraffin wax rubbed into the surface, is clamped on the same turntable as the master or pattern record b, the blank occupying the central portion within the annular recorded surface of the disc b. The tracing-tool q, which is a reproducing-needle adapted to engage the sound-groove of the record b, and the scoring-tool are both carried by holders i, p which are connected by a link 3, clamped by screws 5. The holders are rotatably mounted in plates t, spring pressed against knifeedges v on plates w. These are respectively fixed to the peripheries of discs h, o. The disc h is mounted on a part f, which is jointed at g to an arm d pivoted on a vertical axis at e. The disc h has a socket m into which a stem n on the disc o fits, allowing limited relative rotation of the discs. A slotted link 6, Fig. 5, pivoted to the disc o, and engaging a screw 8 on the disc h, enables the disc o to be held in a raised position, when required, with the needle q clear of the record. Weights l, lx respectively screwed on arms k, r extending from the discs h, o allow the pressures upon the tools j, q to be independently adjusted. The scoring-tool j has a conical end with a rounded point, consisting of a diamond or the like. Specification 1644/78 is referred to.

Title: Improvements in or relating to a process for the production of acetarylamides
IPC: C07C233/00
Filed: 1945-09-20
Abstract: Acetarylamides are prepared by the process of heating acetic acid with an arylamine characterised by feature that the heating is carried out in the presence of a volatile extrainer which is an organic solvent having the property when heated to ebullition in the presence of water of forming a vapourized mixture comprising a substantial proportion of water, the organic solvent being inert with respect to the reactants.  The preferred volatile entrainer is benzene.  In a preferred form of the invention the vapours distilling off from the reaction zone are fractionated to ensure that substantial amounts of reactants such as acetic acid are not distilled with the entrainer-water mixture.  If desired, catalysts known to promote amidation reactions may be present. In examples 1-3 varying proportions of aniline, acetic acid and benzene were reacted to produce acetamilide; (4) the amine used is o-toluidine; (5) the amine used is m-toluidine.

Abstract: A material for use in semiconductor devices (see Group XXXVI), comprises monocrystalline Ge impregnated with 1012-1015 atoms/cc. of Mn but containing less than 2 x 1015 atoms/cc. of uncompensated donor activators.  P or N type material may be prepared by seed crystal withdrawn from a melt consisting of high purity germanium to which high purity manganese and an alloy of high purity germanium with 0.005% by weight of arsenic have been added, the conductivity type depending on the relative proportions of arsenic and manganese in the melt. Electrical contacts to a body cut from the resulting ingot may comprise tin alloyed with 1% by weight of antimony, phosphorus or arsenic, or indium alloyed with 2% by weight of arsenic, phosphorus or antimony.  Instead of using high purity fermanium in the melt impure germanium may be used, the uncompensated donor impurity contact being brought to the desired level by addition of a suitable amount of donor or acceptor impurity as determined by Hall coefficient measurements on a trial ingot grown from the impure melt as described in Group XXXVI.
